Its about benefits. 125k is quite low for high risk jobs for the awesomeness you require. My job offers the same salary with significantly more stability and not so insane requirements.
Zero. Its not a startup. But you can't really get a better healthcare plan, retirement benefits, life insurance, and stability anywhere (most of which is included in your salary already). For example they don't match your 403(b) contributions, they just give you a few grand a year regardless. TONS of PTO. In any case, my point is that for the requirements they should probably pay appropriately, or they just might not attract the people they hope to. Remember not everyone cares about the startup mentality, many just want the job/pay, especially if the job does not want overtime and such. Then again you take no risk, you get no percentage.
